Same here, even with 1.5.1 (official and non) I got occasional lockups but then I ran the maint. scripts through Onyx and everything is normal again. I also rebuilt all desktop files and launch services...stuff like that.

You know, just hit the major points...I'd like to try one on an idle machine.

Well the first points would be to make sure that all the necessary things needed to build Camino are installed and correctly working (in the Terminal app).
See the build notes for Camino here. It's quite simple if you can follow the notes ok.
